After doing a couple searches, the most I could come up with is people looking how to install a HLSD, wasnt really getting a clear picture of what it is or the differences.

Would someone take a couple moments to explain the difference between:

LSD/VLSD/HLSD?

LSD = Limited Slip Differential, not sure what the V or H is abbreviated for?
What are the advantages / Dis Advantages?

Also would a LSD Tranny be a Locking or Non Locking Transmission

Thanks in advance

maximas arent the only cars with limited slip diffs

do some reasearch...www.google.com

to get you started....the H is for helical

^^ excellent article. V=Viscous H=Helical

 

Uh I know what a LSD does. I just need clarification on my questions.

 

did you even bother to read the article?

and judging by this question you don't know what it is:

 

Its funny that you posted that link because before I posted my question, that exactly where I went to and yes I did read everything availible regarding the subject. However with that being said, it doesnt mean i will understand everything the first time I read it. That is why Im asking the maxima community for some clarification.

ok so ive been nice up until now.

For future posters, If you feel like flexing your big maxima.org muscles and pissing testosterone all over my thread with out any intention of helping me, dont.

No one appreciates it, and it embarrasses this community. It also gives off a none inviting atmosphere for all new comers.

Think before you post.

 

i just thought...now im posting

we tried to steer you in the correct direction...but as always...you want people to spoon feed you. donating members dont get spoon feed

 

You can think, but not read apparantly. here let me help you out:

Notice "intention to help".......I guess not...

 

i can read too...i can also post.

i had an intention to help http://forums.maxima.org/showpost.ph...75&postcount=2
but you want someone else to do your research. not gonna happen.

 

give a man a link.....help him for a day
teach a man to find the info....help himself (and all of us) for a lifetime

 

are you freaking kidding me? You did not read that link and it explained everything you asked. Dont get pissy with me for attempting to help your stubborn @ss...

but now he has to read all of that!!!!

 

Maybe we should make the whole Org read only with no ability to post new threads or respond to existing threads. That might cut down on some of the internet rage going on. Every time someone asks a question lately it turns into a flame thread with people having temper tantrums over it.

If I came across this thread as a new member I'd seriously consider whether I wanted to donate or even stay a member.

 

VLSD = viscous limited slip diff
HLSD = helical limited slip diff

HLSD>All

 

or....read and follow the rules

 

I have a 2001 20th AE with 5-speed and VLSD. This design still allows a lot of slip of one drive wheel, particularly when exiting a right angle turn. I suspect making it more aggressive would have had the Nissan lawyers nervous about loss of control accidents caused by excessive understeer. I'd be interested to hear if anyone with the stock HLSD in the '02 and later with 6-speed has similar experience.

I've noticed that it does make a difference when exiting certain, less sharp corners compared to the Honda I had before it; and it seems to help a little with putting power down to both wheels when accelerating in a straight line.

I've never heard of any fwd car with a locking differential; and I suspect there never will be one.

 

You'll get that with VLSD as it's not quite as efficient as a torque-based LSD. Particularly as the fluid is overheated, they lose the 'life' they once had. Eventually they will fail and act similar to an open differential.

Helical, on the other hand, is mechanical and torque-based and works much more efficiently, and is more reliable.

 

Care to elaborate? I gave him two very informative articles but he chose not to take my advice and read them. If he would have read those articles he would have known much more about any type of LSD than the average person.

 

and a thread didnt need to be started to find the info you posted

 

Do all 02+ 6speed trannies have LSD. Which type the viscuous or helical?

 

Nope it's very rare. It's helical if we have them.

 

ok any easy way to tell if my 02 has it. Serial/VIN or something to that nature.

 

look at the last digit of the transaxle code
A - open dif
H - HLSD

 

cool thanks. Can't wait to get home and look. I'm stuck in Brazil working. I was just waiting for somebody to tell me to get in the car and do a burnout. Already did they but like alot of cars it still burns off both tires.

 

It's a rare option on the U.S. cars. It does make a big difference in handling and off the line acceleration.

Some people will say it doesn't make a big difference but I did a tranny swap to get it and couldn't be more pleased. 1st and 2nd gear are more useable under hard straight line acceleration. When punching it in a turn I don't get one wheel spinning anymore. The car just hooks and pulls through the turn.

LA02MAX, after rereading the begining of the thread (especialy post#6) I agree he was out of line. In this case it was justified.

 

maybe I got lucky then I havn't had any traction issues in mine yet. Or the previous owner babied it too much and it's underpowered.

Anybody notice that nissan 6 speeds with or with LSD have better traction in 1st that the automatic counterparts. every Automatic 03 Max I've driven could not hook up in 1st. I had a 350Z as a rental 3 weeks ago and if it didn't have traction control it probably wouldn't be very drivable as the slip light was flashing constantly in the first two gears. My 02 Max and the few 6 speed 350z's I've driven I almost couldn't get them to lose traction.

 

damn, it could be that you have some good tires or something. If I floor it in 1st at any speed, it burns all the way through so I really have to modulate the throttle. At the track, it spun through first, most of second, and a couple seconds into third New tires are definitely on my to-do list.

Where you'll notice the LSD most is in the corners. In a straight line, it actually robs a bit of power and unless the road is really uneven/bumpy it won't help as much.

 

I can't imagine that the tires are very good. Dealership put new Continental all season on. Although it spins pretty friggin good if I slam into second.

 

If I use full throttle in 1st or most of second it'll still break traction. It makes those gears more useable though. I noticed a big difference at the drag strip too. With drag radials I can really punch it in second and it will hook. It would never do that before the swap. I've managed around 13.8 in the 1/4 so I'm not lacking power.

I also notice it when driving in the rain. I can push it harder in a straight line before it looses traction. When it does it still wants to go straight instead of jerking to the right. I'm talking about having traction and dipping into the throttle to spin the tires.

These are just my experiences having had both types in the same car.

 

Yeah that's another point I forgot to make about the wet traction. What about torque steer? Did you notice any difference? The only time I experience torque steer is when I get really good traction on certain roads, but I actually kind of like the feeling

 

The torque steer is a lot more under control since the swap. I really think all the manual Maximas should have had HLSD standard. The car is just all around better with it.

As an update I just had a new set of Toyo proxies4 installed Saturday. These won't break loose in second at all once I have traction after the shift. I can start at a low RPM and nail it with traction all the way to redline. I couldn't do that with an open diff no matter what tires I had. Even the drag radials. Keep in mind that I have an 04 tranny with lower gearing so it should be easier to spin the tires. I think as you start adding power the HLSD becomes more important even in good conditions.

 

or....we could all sit around waiting to jump on anyone that DARES to post or question the maxima god.

Meh, whatever.

Isn't this why it's called a *message* board? Why else did we PAY for this board?

Ask questions, get replies....that's how polite conversation works in a civilized society. Why is it so offensive to ask a question? Search is NOT perfect....it's sometimes hard to get an answer....but god forbid you aren't an expert at using it like someone who uses it 490 times a day.

 

I was told i got an LSD and i got told what it was but im going to check ou that link you gave LA02MAX .. and even found more information about etc stuff i want to learn about . SO THANKS !!!

When I try to burn out of the line on a straight away .. Sometimes my tires bounce alot is that the LSD or my not knowing how to burn out lol.. I got Hankook Tires on there now i used to have michelin and still did the same..

 

^That's called wheel hop. Polyurethene motor mounts will help the problem, but few things will cure it (lowered drivetrain, traction bars, etc.).

If you have LSD it will be the viscous type, which as I mentioned will wear out over time in many cases. Check the firewall and look at the transmission code. If it says V at the end of it, you have VLSD. If it says A, you have an open diff.

 

I try researching what Lowered drivetrain, traction bars are.. no luck any help.?I checked my Engine Sticker and yeah i got a VLSD
